Lady Gaga, you have arrived. Like Beyonce’s “Single Ladies,” Gaga’s “Poker Face” has become so wildly popular that even Christopher Walken has jumped on board covering it. This tribute does make us feel slightly uncomfortable and we hope Walken sticks to acting. But admit it, when Gaga busts out this song in the club, you can’t help but dance. After the jump, a few more amazing odes.

You can’t deny that Lady Gaga certainly has her own interesting fashion sense. But now, on top of her latest antics (like selling a piece of her hair to fans), she’s taking on the style of Hello Kitty. Eh, somehow we’re not surprised. It’s all for the character’s 35th birthday, yet the pictures by Markus Klinko and Indrani will appear on the cover of her special, limited-edition reissue album. You can also catch them in Los Angeles, on display at the Three Apples birthday exhibition. Maybe the precious Sanrio kitty will make an appearance during her tour? [Daily Mail]

Tired of walking past buildings when you’d rather wear one? Joshua DeMonte steals architectural elements to create totally out-there accessories. A banister winds around a wrist. A staircase adorns a neck. A curtain-billowing window becomes a bracelet. Surely not for the fashionably shy, one imagines how long it’ll be before we see Lady Gaga wearing one of these creations.

Get your spirit fingers ready! Today’s episode of “It’s On With Alexa Chung” is gonna be super-duper gay. [Twitter]

Oh Lady! Gaga looked like she was still in a Halloween state of mind at the Accessories Council’s ACE Awards yesterday evening, where she was presented with a Stylemaker award for her “genius” use of extraneous ornamentation. Sadly, wigs were harmed in the making of this headpiece. [NYC, 11/2/09]

Was your neighborhood overrun with Lady Gaga impersonators this Halloween? For all those crazy fans out there, the wig-wearing diva is giving up a strand of her real hair to make their dreams come true. She’s selling a deluxe box set—complete with the book of Gaga, “The Fame” album, eight new songs, 3D glasses, and to top it all off, a lock of her hair. The price tag on this Gaga-licious item is $114.98. No word on where the money is going, but we’re pretty sure it’ll be added to the funds for her crazy costumes. We say this is way creepy. It was weird enough when Elvis sold his hair, but oh wait, he was dead already and he is also the King. Thoughts? [Mirror]

Alright, I know I’m a little late to the party on this one, but this quick little snippet from “South Park” kept cracking me up during my post-Halloween hangover on Sunday. Cartman meets Lady Gaga, a match made in ... God knows where.

It’s no wonder Lady Gaga has reportedly gone bankrupt four times because quite a bit goes into her extravagant everyday looks. Homegirl loves her crazier-the-better accessories! After the jump we’ve got the deets for how to get the perfect Lady Gaga costume with things possibly in your closet already and items you could totally wear again (either with more clothing or while role-playing).

Yesterday was the Marriage Equality March in Washington, D.C. as gay rights activists came out in droves to demand the right to get legally married in the United States. Many celebs were on hand, including Lady Gaga, who gave the speech above. Props for the Judy Garland joke, G! [Los Angeles Times]

In other gay rights news, at a human rights dinner this weekend, President Obama vowed to end “Don’t Ask, Don’t Tell,” the 16-year-old policy which bans gays from serving in the military if they are openly gay. About. Effing. Time. [Wall Street Journal]

If you saw “Saturday Night Live” last week, you know that Madonna and Lady Gaga had a fake makeout sesh. But on Sunday night, the two pop stars had a real life dance-off at a New York City club! The DJ, Jus Ske, started alternating “Holiday” and “Poker Face” while the ladies got down on the dance floor. An onlooker said, “Madonna seemed to be the winner. People were going wild.” No kidding Madonna won. Lady Gaga only has one dance move and it’s creepy. If only someone had a camera phone video! [NY Post]

Thankfully, plenty of other celebrity dance-offs have been recorded and are actually pretty hilarious!

We thought we’d have to commit group suicide if we heard one more thing about Lady Gaga’s pantslessness. The girl isn’t a fan of bottoms. We get it.

But the ever-amusing ladies over at Refinery 29 have turned pantslessness into more than another boring trend post with their latest chart: Bye Bye Bottoms!. This fine piece of work is nearly academic in its historical look at the evolution of the hemline from dowdy long to non-existent. Check it out and tell us: what’s your favorite length era? [Refinery 29]

As we reported yesterday, Alexander McQueen‘s big live-streaming fashion show was ruined by Lady Gaga when she let it slip on Twitter that her new single, “Bad Romance,” would premiere there. Unfortunately, unless you’re a fashion editor or part of the style elite, you didn’t get to see or hear anything because the rush of Gaga fans to the website caused it to crash. So without further adieu, here’s what you missed. Do we likey?

Alexander McQueen was all set to revolutionize insider-y Fashion Week by broadcasting his spring/summer 2010 runway show live on the web. The fashion blogs were psyched, and so were we. Unfortunately, fashion history was not made, and who should be at fault but Lady Gaga. When the pop star posted to Twitter that her new single, “Bad Romance,” would be debuting at the McQueen show, the streaming website was inundated by thousands of visitors, causing it to crash.

No fashion for the masses this time, kiddies. Maybe next season designers who want to stream their shows live will think about increasing their bandwidth (and no, that doesn’t refer to dress size). [Elle UK]

If Lady Gaga didn’t end up winning over some of her haters last night, after performing on “Saturday Night Live,” then they’re a lost cause. The pop diva absolutely knocked it out of the park, performing both “Paparazzi” and a medley of her songs, including “Poker Face” (in a gyroscope-enabled dress, natch)—showing off not only her ability to put on an entertaining show, but also her singing talent. Madonna showed up to join Gaga in one of my personal favorite regular skits, “Deep House Dish,” which came off a little awkward, but still was a nice little endorsement from the Queen of Pop. Clip of that, after the jump.

Let the style wars begin: Beyonce was the artist being honored at this Billboard Women In Music Awards brunch, but is it just us or did Gaga slightly overshadow her on the red carpet? Then again, we'd never suspect the two women were dressed for the same event (except, of course, for the "Billboard" backdrop), especially given the fact that this was essentially, like, a breakfast. Thoughts anyone?

Live Nation has confirmed rumors that the Lady Gaga-Kanye West tour, “Fame Kills,” has been officially canceled. Gossip blog MediaTakeOut is reporting the decision was all Gaga — a probable fall-out from Kanye’s much-publicized VMA meltdown (though she was defending him as recently as a couple days ago). I’m not so sure, though — I can think of 10 other reasons these two would cancel a concert together…

Let’s talk about how mother-effing excited I am for this weekend’s “Saturday Night Live.” Yes, last week’s season premiere totally blew, but tomorrow night, Mr. Scarlett Johansson, aka my second favorite Ryan in Hollywood—Ryan Reynolds—is hosting, with musical guest, Lady Gaga. This shiz is gonna be hot. Promo above.
